Shot in smoldering black and white by photographer duo Mert Alas and Marcus Piggott in New York City, the SS15 campaign features Bieber cozying up to Stone in "key jeans and underwear styles of the season."

There are pics of Stone draped over Bieber's tattooed torso, and it heats up even further with shots of the pair straddling in denim. Bieber also goes solo, channeling a little James Dean attitude, lifting his white shirt to flash the famous waistband on his CK boxers.

Calvin Klein explain that its campaign—which will roll out on billboards, in print, and online as of March—will be their most "digitally-focused to date," making Bieber, 2014's No. 1 most Tweeted-about star, a natural choice for the male lead.

The 20-year-old says of his new role: "Calvin Klein is such an iconic brand and I am excited and honored to become a part of the Calvin Klein brand legacy with this campaign. I have been a longtime fan of the brand and have worn their jeans and underwear for a while, so this is kind of a dream come true.

“This is the beginning of an exciting new year for me, personally and professionally, and being a part of this campaign has been a fantastic opportunity and experience.”

So, does Justin match up to Wahlberg and Dornan? We'll let you decide.
